I came across the oină in one of the Romanian lessons I did today. It’s translated as ‘oina’ without any explanation of what it means. As the lesson was about sport and oină is something you play, I guessed that it’s some kind of sport.
The word oină was originally hoina, and is comes from the Cuman word oyn (game), which is cognate with the Turkish oyun). The game was first mention in writing in 1364. Cuman is an extinct Turkish language that was spoken in Hungary until the 18th century.
